What should USMS do about the suits?

And you are basing this on a comparison to a 3mm full wetsuit? You can get 1mm wetsuits. The high end ones are made from yamamoto rubber, same as the B70. Those are also marketed with as having hydrophobic properties much like the swim skins. Having seen both, there is very little that is different. The only difference is the way its marketed, swim skin vs wetsuit. Eliminate the wetsuit technologies (like yamamoto rubber) and you will have your line to draw. I guess that's a point. I've never seen a 1mm wetsuit though. Do many wear them? I've only seen the 3mm or 5mm in tri stores. In the race I just swam Sunday, I don't recall seeing any super thin ones that looked like B70s at all. The 3 mm or 5 mm are obviously more performance enhancing because they're so buoyant. So OW swimmers can have performance enhancing wetsuits and performance enhancing B70s in the non-wetsuit division, but pool swimmers don't get speed suits?!
